城市地理时空大数据管理与应用平台建设技术和方法研究

针对城市地理时空数据的专业类别多、数据格式多、数据分散等诸多特性，提出了栅格式数据、图形式数据、要素式数据、类GIS数据、ArcGIS数据5大类地理时空数据的管理方案。采用基于富客户端的地图增强技术、基于时间帧的时空数据动态表达技术和空间数据及平台功能自扩展定制技术，对城市地理时空大数据管理与应用平台进行了总体设计，开发了集管理与应用于一体的资源创建与管理系统、信息集成共享系统、数据交互应用系统，实现了城市地理时空大数据的管理与应用的高效性。本文提出的技术方法已在长沙市规划交通勘测信息集成管理与应用共享平台项目建设中得到验证，为城市地理时空大数据的集成管理和共享应用提供了技术经验。

Research on the Technology and Method of Urban Geography Space Time Big Data Management and Application Platform

According to the characteristic of spatial and temporal geographical data on urban, such as multi professional category,multi data format, data dispersion and so on, the management schemes of the grid format data, the data of the graph form, the data of the element type, the similar GIS data and the ArcGIS data of 5 kinds of geography space time data are put forward.Using map enhancement technology based on rich client, dynamic representation of temporal and spatial data based on time frame, spatial data and platform function self expanding custom technology,the overall design of the data management and application platform of the urban geography space time and space is carried out. The trinity system of resource creation and management system,information integration and sharing systems,data interactive application system is developed. The high efficiency of data management and application in urban geography time and space has been realized. The technology method proposed in this paper has been verified in the project construction of information integration management and application sharing platform for planning traffic survey in Changsha city, which provides the technical experience for the integration management and sharing application of the urban geography space time big data.
